I'm interested in Rodmur's answer as well but offhand I'd say:
Fly540 - yes, this company knows what the heck it is doing and will use the right aircraft for the market as well as a good sales strategy.
Fly Kumba, & their new generation fleet of Boeing 737-200s :-) - no. I think they'll end up a bit like another B732/recent entry into the African aviation market: SkyJet Uganda.
Wildcard - You never know what strings Uncle Bob will be pulling.
